[PATCH v6 16/17] media: uapi: Change data_bit_offset definition

[Benjamin Gaignard <benjamin.gaignard@collabora.com>]

'F.7.3.6.1 General slice segment header syntax' section of HEVC
specification describes that a slice header always end aligned on
byte boundary, therefore we only need to provide the data offset in bytes.
